Where are blazegraph data files located? Can they be deleted to fix undeletable namespace?

Somehow we have a namespace that is corrupted and cannot be deleted using the webpage for namespaces (that is about the extent of the message you get...). Where are the blazegraph data files located on disk so I can delete them and restart blazegraph to have them be recreated. I can create and repopulate the namespaces we want... We are running version 2.1.4.

Solution

  • it should be all inside the bigdata.jnl journal file

    • if you are using the .jar executable, the journal file created in the same folder
    • if you are deploying in a container i.e. Tomcat it should be somewhere inside /etc, /opt, /usr or near CATALINA_HOME

    EDIT: you can find more info about the .jnl file here https://github.com/blazegraph/database/issues/41
